As part of the VAMOS[0] research project at the University ofErlangen we're checking referential integrity between kernel KConfigoptions and in-code Conditional blocks.

Git commit 0b1b213fcf3a8486ada99a2bab84ab8c6f51b264 byChristoph Hellwig removed all References to CONFIG_XFS_TRACE, which isunreferenced from KConfig side from the linux source code so there'sonly a small bit of it left in KBuild. Mayee remove it as well?

./fs/xfs/Makefile:95+++>

xfs-$(CONFIG_XFS_TRACE) += xfs_btree_trace.o

<+++

Please keep me informed of this patch getting confirmed /merged so we can keep track of it.
